What’s Important in an AR-15 Laser?

Let’s talk a little bit about what you need to know before jumping in and buying an expensive (or inexpensive) laser sight for your AR.

Ease of Installation

First up, let’s chat about installation. You don’t want a laser sight that requires an engineering degree to attach to your rifle. Look for sights with simple, user-friendly mounting systems that can attach to standard Picatinny or Weaver-style rails. Most AR-15s come equipped with these, so you should be good to go. A sight that’s easy to mount will save you time and let you get back to what you love doing – shooting!

Visibility and Range

Next up, visibility and range. Not all lasers are created equal, and this is especially true when it comes to their visibility. Green lasers tend to be more visible than red ones, especially in brighter conditions. As for range, make sure the laser sight offers a clear and precise aiming point at the distances you usually shoot. Remember, a laser sight’s effectiveness is heavily influenced by its range and visibility, so keep this in mind when making your choice.

Durability and Resilience

Let’s not forget about durability and resilience. Your laser sight needs to be tough enough to withstand the recoil of an AR-15 and robust enough to handle the elements if you’re an outdoor shooter. Look for sights that are shock, dust, and water-resistant – these features will ensure your sight can take a beating and keep on ticking.

Battery Life and Operation Modes

Battery life and operation modes are also crucial considerations. You don’t want a sight that’s going to run out of juice in the middle of a shooting session. Consider sights with good battery life and preferably ones that offer different operation modes, like constant on, strobe, or momentary. This will give you the versatility to adapt to various shooting scenarios.

Price and Value

Finally, price and value. While it’s tempting to go for the cheapest option, remember that with laser sights, you often get what you pay for. Balance cost with the features and performance you’re getting. Sometimes, it’s worth shelling out a little more for a sight that will last and perform better in the long run.

Laser Color

Here’s a hot topic that’s worth discussing – the color of the laser. You’ve probably noticed that laser sights come in two main colors: red and green. But what’s the difference, and does it really matter? Well, in a nutshell, yes, it does!


When it comes to visibility, green lasers generally have the upper hand. The human eye is more sensitive to light in the green spectrum, meaning a green laser will typically appear brighter and more noticeable, especially in daylight conditions. Red lasers, while still effective, may be harder to see in bright light. However, they often perform just as well as green lasers in low-light or night-time scenarios.

Laser Color vs. Battery Life

However, the color isn’t just about visibility. It also impacts battery life. Green lasers consume more power than red lasers, meaning they might drain your batteries faster. So, if you’re planning to use your laser sight extensively or over prolonged periods, a red laser might be more energy-efficient. But remember, advancements in technology are continually improving the battery life of green lasers, so don’t rule them out just yet!

Price Point of Red vs. Green Lasers

Lastly, let’s touch on price. Green lasers, with their superior visibility, often come with a higher price tag than their red counterparts. But is it worth the extra bucks? Well, that depends on your specific needs and shooting conditions. If you frequently shoot in bright, daylight conditions, shelling out a bit more for a green laser might be a worthwhile investment. On the other hand, if you’re more of a dusk till dawn or indoor range shooter, a red laser should serve you just fine and save you some change.

Choosing the right laser sight for your AR-15 can significantly enhance your shooting experience. With these considerations in mind, you’re well on your way to finding the perfect laser sight for your needs. Stay tuned as we delve into our top picks for the best laser sights for AR-15s in the next section!

I’ve been using this green laser sight on my AR-15 for a while now, and it’s been nothing short of outstanding.

Easy Installation

First things first, the installation. This rail-equipped wonder is incredibly easy to mount, with a simple attachment mechanism that’s compatible with the Picatinny and Weaver-style rails commonly found on modern rifles. I had it secured to my AR-15 in no time, straight out of the box, without any need for a gunsmith.

Excellent Adjustment Dials

The adjustable windage and elevation dials are another great feature. They’re user-friendly and make zeroing in the laser a cinch.

I’ve had issues with other sights losing their zero after repeated use, but this is one area where the CMR-206 surpasses the competition.

I’ve used the sight quite a bit, and I’m yet to replace the batteries. The automatic shut-off feature after five minutes of inactivity is another thoughtful addition that helps to conserve battery life.

Quality Comes with a Cost

Now, it’s worth noting that the CMR-206 comes with a bit of a hefty price tag. But after using it for several months, I can confidently say that it’s a worthy investment. The superior build quality, excellent visibility, easy installation, and impressive performance more than justify the cost.

So, if you’re in the market for a reliable, high-quality laser sight that will take your shooting to the next level, I’d highly recommend the Crimson Trace CMR-206. It’s a compact powerhouse that’s proven its worth in every aspect, and has firmly secured its place on my AR-15.
